Study on the germination conditions of Bromus cartharticus

The influences of different temperatures, germinating beds and lights on the germination characteristics of Bromus cartharticus were discussed in germination test. The conditions of temperatures included seven constant temperatures (10、15, 20, 25, 30, 35 and 40 ℃) and two alternating temperatures (15/25 ℃ and 20/30 ℃), light treatments included darkness (0 lx) and 2 000 lx light intensity, and bed treatments were carried on the top of paper（TP）, between of paper(BP), top of sand(TS) and between of sand(BS). The optimum seed germination temperature of B.cartharticus was 25～30 ℃, TP was the best bed and light insensitive.
